DETAILED DESCRIPTION

Embodiments of the present electronic cigarette will now be described indetail below and with references to the drawings.

Referring to FIGS. 1 to 3, an electronic cigarette in accordance with afirst embodiment is provided. The electronic cigarette includes abattery assembly 1 and an atomizing device 2.

The atomizing device 2 has a tobacco solution containing space 4, and aheating assembly 6 configured for heating the tobacco solution. Theatomizing device 2 further has a connecting portion 7 protruded from anend thereof The connecting portion 7 is ring-shaped, and has anelectrode ring 5 positioned therein. In the present embodiment, an outerwall of the connecting portion 7 is flat and smooth, and the connectingportion 7 is made of a ferromagnetic material, such as iron, cobalt,nickel which can be magnetized and can be electrically conductive.

The battery assembly 1 includes a receiving space 3 defined at an endthereof, an electrode ring 9 positioned in the receiving space 3, amagnetic block 10 and an insulated ring 12. The magnetic block 10 ispositioned in the receiving space 3 around the electrode ring 9, and theinsulated ring 12 is located between the electrode ring 9 and themagnetic block 10. The magnetic block 10 can be a permanent magnet.

In assembly, when the connecting portion 7 of the atomizing device 2 isinserted in the receiving space 3 of the battery assembly 1, due tomagnetic attraction between the connecting portion 7 and the magneticblock 10, the atomizing device 2 and the battery assembly 1 can beconnected quickly, therefore the electrode ring 5 can contact theelectrode ring 9 for electrical connection, and the heating assembly 6can work for heating the tobacco solution in the atomizing device 2.

In the present embodiments, the receiving space 3 is provided by aring-shaped magnetizable member 8, such as an iron member or magneticceramic, thereby a magnetic force of the battery assembly 1 can beenhanced. An inner wall of the receiving space 3 is flat and smooth. Themagnetizable member 8 can be electrically conductive, or insulated. Whenthe magnetizable member 8 is electrically conductive, the connectingportion 7 of the atomizing device 2 can be electrically connected to themagnetizable member 8. When the magnetizable member 8 is insulated, theconnecting portion 7 of the atomizing device 2 can be electricallyconnected to a metallic battery sleeve of the battery assembly 1.

In other embodiments, the receiving space 3 can be directly provided bya battery sleeve of the battery assembly 1.

In addition, in the present embodiment, an elastic member 11 is appliedto the electrode ring 9 of the battery assembly 1, that is, theelectrode ring 9 is fixed by the elastic member 11 in the insulated ring12. The elastic member 11 can be selected from a group consisting ofspring, resilient sheet and silicon rubber ring. Due to the elasticityof the elastic member 11, the electrode ring 9 can stretch out and drawback, such that a contact between the electrode ring 5 and the electrodering 9 can be tightly, and therefore a good electrical connectionbetween the electrode ring 5 and the electrode ring 9 can be attained.In addition, due to stretchable elastic member 11, a connection depthbetween the battery assembly 1 and the atomizing device 2 can beadjusted.

Referring to FIG. 4, an electronic cigarette in accordance with a secondembodiment is provided. The electronic cigarette of the secondembodiment is essentially similar to the electronic cigarette of thefirst embodiment, only differs that an atomizing device 2 of theelectronic cigarette of the second embodiment also has a magnetic block10, and the magnetic block 10 is arranged near a connecting portion 7 ofthe atomizing device 2.

Referring to FIG. 5, an electronic cigarette in accordance with a thirdembodiment is provided. In the present embodiment, a battery assembly 1has a connecting portion 71 protruded from an end thereof, and anatomizing device 2 has a magnetizable member 81 having a receiving space31. The connecting portion 71 is preferably made of a permanent magnet.In assembly, the battery assembly 1 is inserted into the receiving space31 of the atomizing device 2, and the connecting portion 71 is quicklymagnetically attracted by the magnetizable member 81. A magnetic block10 can be avoided in present embodiment.

By the above magnetic connection, threaded connection can be avoided.However, in some situations, upon the magnetic connection, a shortdistance of threads is not excluded to each of the battery assembly 1and the atomizing device 2 to enhance the connection.
